A number of applied psychologists have suggested that trainability test Black-White ethnic group differences are low or relatively low (e.g., Siegel & Bergman, 1975), though data are scarce. Likewise, there are relatively few estimates of criterion-related validity for trainability tests predicting job performance (cf. Robertson & Downs,…

Background: Facing growing accountability pressures, Teacher Work Samples (TWSs) as a model of performance-based assessment is of growing significance in teacher education. Developed at Western Oregon University and widely adopted and adapted, proponents claim that the model is "real," "natural," "meaningful," and "helpful" (G. R. Girod, 2002).…

Acknowledging the necessity to establish the fairness and consequential validity of teacher candidate performance assessments when they are used to make high-stakes decisions impacting entry into the profession, we investigated whether there were any adverse results from the use of the Renaissance Teacher Work Sample (TWS) assessment at two…

Large-sample item response data for the 10-item Paper Folding worksample 622 (N=2,749) and for five new experimental paper folding items (N=2,514) are analyzed with the logistic item response model and with full-information item factor analysis. The main results of the unidimensional analysis are that: (1) item discrimination is heterogeneous, so…

The construct validity of written Ideaphoria and oral Ideaphoria is discussed through analysis of their content and format and their correlations with tests of divergent thinking and writing speed. The current status of research on the measurement of divergent thinking ability is reviewed. Although the Ideaphoria tests have the same content as…

An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning. Subjects, who ranged in…

A project was conducted to develop and assess a highly job related personnel selection battery that could be administered to inexperienced applicants for positions as public assistance workers in departments of public welfare or unemployment offices. The Public Assistant Worker Job Trial (PAWJT) is called a job trial because instead of attempting…

As part of an effort to provide more economical methods for job-skill evaluation in the Army Enlisted Personnel Management System, a study investigated the use of television as a means of presenting test items for a sample of tests from the job field of tank crewman. The television scene provided the job setting for each item and then posed a…

The use of a performance-based assessment of senior medical students' clinical skills utilizing standardized patients was evaluated, with 6,804 student-patient encounters involving 405 students over 6 years. Results provide evidence for test security, content validity, construct validity, reliability, and test ability to discriminate a wide range…

A study was conducted (1) to obtain an estimate of the amount of error in prediction that occurs when static measures are used to interpret work-sample performance; (2) to identify a number of dynamic performance measures that reflect learning that might occur on the task; and (3) to compare the predictive accuracy of those measures to that of…

A test development plan is described to evaluate police enrolled in the law enforcement basic training course developed by California's Commission on Peace Officer Standards and Training (POST). Some general test methodologies are discussed: performance tests, knowledge tests, and situational tests, including role playing simulations and…

A prototype simulation measure of the negotiating skill of interpersonal competence is described, and results of an initial validation study are reported. Of eight negotiating skills identified by the Secretary's Commission on Achieving Necessary Skills of the U.S. Department of Labor, two were the focus of the measure: proposing and examining…

A battery of work sample tests, the Micro-TOWER System of Vocational Evaluation, has been developed for use in vocational and career education programs. Verbal, numerical, and perceptual motor skills useful in various occupations are measured. The system has been field tested in vocational rehabilitation centers, prisons, schools, and psychiatric…

The Micro-TOWER System of Vocational Evaluation was developed in response to the need for a revision of the TOWER (Testing, Orientation, and Work Evaluation in Rehabilitation) System. The Micro-TOWER system of work sample tests measures the major aptitudes required for most semi-skilled and unskilled occupations. It may be used as a screening…

These conference proceedings contain statements from those concerned with various aspects of research on job performance measures. Following introductory remarks, the formal presentations of work and ideas include "Air Training Command Interest in the Criterion Problem," by Donald E. Meyer, "The Criterion Problem: A Personnel…
